Inverter With Battery Bank In Solar Farm System

SunKo technical engineers need to tell all of you, a solar farm with batteries ensure that the power delivered to the inverters is stable DC power. The way these systems are installed is. The solar modules are connected to DC to DC charge controllers. The charge controllers are connected to the battery banks. The battery banks are connected to large 3 phase inverters. The inverters are connected to 3 phase transformers that convert the volts and amps into KVAs. The KVA can go to the substation or transfer station. The transfer stations are grid connected to either the main grid or mini grid or micro grid. The batteries are supplying the inverters stable volts and AMPS. Thus is a cloud or something that would shade the panels the power stays the same because the batteries are the stable source of electric power. Thus there is no power loss due to clouds, fog or rain.

These type of systems we call "Solar Power Plants", not solar farms. Solar farms have no storage thus a solar farm is totally dependent upon the sun to supply power directly to the inverters.

The wave form must be at all times pure sine not some modified sine. A true off the grid solar system is just like a solar power plant except for us matches the electrical loads 24 hours a day. Sometimes in areas of the world we have to have up to 72 hours storage because of ice storms, coastal fog or areas where you can get 140 to 200 inches of rain a year. Almost all silicon solar farms can only produce max 6 hours a day under ideal conditions. We don't live in that world. Most silicon solar farms can at best produce 5.2 hours a day. Our solar power plants supply electric power 24 hours a day just like a fuel fired power plant. Remember a solar farm really has no moving parts nor does it require fuel to produce electric power. We convert the sun's energy into electric power directly without the use of water or fuels. Thus when it comes to ROI subject we will win every time.

Some people think that a solar farm cost more than a coal fired, diesel fired or nuclear power plant. This is not true. When you take the cost of fuel out of the math and high cost of a coal fired power plant a solar power plant cost less and it more reliable than any other form of electric power generation. The next best thing is a hydro power plant. The water behind the dam is stored energy, same as a bank of batteries.
